Recently, there have been many researches about Autonomous Underwater Vehicle (AUV) which is imitated motion of aquatic lives. We have been developed an Eel-like robot that swims by anguilliform swimming on the water. In this paper, to add the function of diving for Eel-like robot, we developed 2DOF neck mechanism. In the experiment, it observed that the Eel-like robot could dive while swimming with bending neck down. The results shows, diving speed could control by change the angle of neck.
